How to use an S4/Hana OData service in Analytics Designer?

Analytics Designer complements SAC stories by allowing to respond to very specific scenarios.
One of these scenarios is to be able to explore and analyze data following an alert sent by the system (for example a sales revenue warning). Then be able to make simulations to correct this problem (review the material prices) and finally validate the option that solves the problem (update the material prices).
This workflow is called a close loop scenario. It basically gives the power to a business user to do a what-if analysis and to take a concrete action based on his simulation.

 
In this blog post I will show you how to implement an ODataService in S/4Hana and how to call it from an Analytic Application. I will use a well-known demo at SAP called BestRun Bike.

Demo context

The demo shows BestRun Bikes company tracks, analyzes eBike sales performance issue using SAP Analytics Cloud analytic application and takes the insight into action to improve the sales revenue.

The highlighted features include:

• Embed Explorer, Smart Discovery, R visualization in analytic application
• Call OData actions in the backend S/4HANA system via scripting

I will concentrate the rest of the blog post on the OData part. In this demo all the product prices are read from the S4HANA system using OData Function

In the simulation&planning page we, can see that the sales revenue based on current prices is showing red alert compared to budget.

During the analysis of the eBike sales performance, we can see that the MZ-FZ-E211 eBike model has a much higher price than competitive products.

To adjust the price to the competition, we can run a simulation on the eBike prices. In our simulation we reduce the price by 15%.

This has the effect of increasing the forecast revenue and the quantity sold in a positive way. We need to update the price based on our simulation. The good news is that to change the price you don’t need to go into the S/4Hana system. Thanks to Analytics Designer you can directly call an OData service that has been implemented in S/4Hana system. To do so we just need to click on the “Update” button

 

Create an OData Service in S/4HANA

In S/4Hana you can use 2 versions of OData : version 2 and version 4. In order to write back data you need to use the OData V4 version. In this blog I will explain what are the main steps to create an ABAP OData Service. If you want to have more details regarding the implementation of an OData V4 Service please have a look here

To be able to consume the S/4Hana OData service in this demo we had to:

1. Create ABAP CDS view
2. Create ABAP OData Service and implement ABAP classes
3. Test the OData Service URL

Create ABAP CDS View
For this demo we created 2 ABAP CDS views that read the data from a Pricing table:

• ZMATERIALCOND : Base CDS view to read Material Condition Records

@AbapCatalog.sqlViewName: 'ZMATCONDRECORD'
@AbapCatalog.compiler.compareFilter: true
@AbapCatalog.preserveKey: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Material Conditio Record'
define view ZMATERIALCOND as select from a304 join konp on a304.knumh = konp.knumh{
key a304.matnr as Material,
a304.knumh as ConditionRecord,

@Semantics.amount.currencyCode: 'Currency'
konp.kbetr as Amount,

@Semantics.currencyCode: true
konp.konwa as Currency,
konp.kpein as PriceUnit,
konp.kmein as UoM     
    
}
where a304.kappl = 'V' and a304.kschl = 'PPR0' and a304.vkorg = '1710' and a304.vtweg = '10' and konp.konwa != '';

• ZMATERIALPRICE : Consumption CDS view to join Material Valuation & Condition Records

@AbapCatalog.sqlViewName: 'ZMATPRICE'
@AbapCatalog.compiler.compareFilter: true
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Material price'
@OData.publish: true
define view ZMATERIALPRICE as select from mbew join ZMATERIALCOND on mbew.matnr = ZMATERIALCOND.Material {
 
 key mbew.matnr as materialno 
 ,
@Semantics.amount.currencyCode: 'Currency'
mbew.stprs as StandardPrice,

@Semantics.amount.currencyCode: 'Currency'
mbew.verpr as PeriodicUnitPrice,

@Semantics.amount.currencyCode: 'Currency'
mbew.vjstp as StdPricePreviousYear ,

@Semantics.amount.currencyCode: 'Currency'
ZMATERIALCOND.Amount as ConditionAmount,
@Semantics.currencyCode: true
ZMATERIALCOND.Currency as Currency 

// ZMATERIALCOND.PriceUnit as PriceUnit,

//ZMATERIALCOND.UoM as UoM
   
}

To expose these CDS view to external application, we created an ABAP OData service. To do so, you need to type the Transaction Code : SEGW in the S/4Hana System

Create ABAP OData Service
Then we created a new OData service. You need to select the Project Type= OData 4.0 Service.
In our example, we called the project zanalytics_material

Add EntitySet, Entity and OData actions
Once the service has been created we added an entityset called MaterialPriceDataSet and an entity MaterialPriceData

We also needed to implement 2 mandatory classes :

• The model provider class  (ZCL_ZANALYTICS_MATERIA_MPC_EXT)
• The data provider class ( ZCL_ZANALYTICS_MATERIA_DPC_EXT)

In the MPC EXT class we declared a new action called “MaterialPriceUpdate“ (line14). This is the action that is called by the analytic application

Here is an example of the implementation for this class

Test the OData service URL
Once the OData service has been implemented you can call it from a URL. To retrieve this URL you can type the transaction code = /n/IWFND/V4_ADMIN

This transaction code is to open OData v4 services. Here you can see list of OData v4 services available in the system and also test them

Then you need to select  “ZANALYTICS_MATERIAL” entry and click on Service Test -> Gateway Client

 

Call an S/4Hana OData action from an Application

In Analytics Designer in SAP Analytics Cloud, you can define OData Services based on an existing live connection in your system which was created using CORS (Cross-origin resource sharing) connectivity

Before calling the OData action “MaterialPriceUpdate“ (that we have defined in our S/4Hana system) from an application the main steps are:

• Define the CORS configuration to your system according to the help page.
• Additionally: Configure support for “if-match” as allowed header in your system.
• Define a direct connection to this system.
• Open an application and add an OData service technical component

Regarding the CORS configuration for S/4Hana system you can consult the following blog

Define a direct connection to this system
In our SAC system we declared a S/4Hana connectivity where we specified different parameters:

• The name of the connection = S4OPHE4
• The connection type = Direct
• Host: cihe4.internal.sde.cloud.sap
• HTTPS Port: 50081
• Client: 400

And we used the SAML Single Sign On authentication method.

 

Add and configure the OData Services technical component
To be able to call the OData service we needed to create an OData Service technical component in the application. This component has few properties:

Name: name of your technical component
Connection: connection to the S/4Hana system
End-Point URL: OData Service URL generated in S/4Hana

In an analytic application in the Layout Outline in the Scripting Section you can create a new OData Service by clicking on plus button.

In the side panel you can change the name, select the System from the list of available systems whose connections are already created in SAC under Connections, and specify the End-Point URL of the OData Service manually.

In the Metadata section you see all the Entity sets and Actions expose by the OData service. We find well the action “MaterialPriceUpdate“ that we defined previously in our S/4Hana system

 

Call the OData action
In the demo when we click on the “Update” button we use the following code to call the “MaterialPriceUpdate” action.

 The executeAction method accepts 2 arguments:

• Name of an OData Action (in our case MaterialPriceUpdate)
• Parameters (in our case price and Material)

When this method is called then the price is udpated on the S/4Hana system side.

We can check that the price has been correctly changed in the S/4Hana system. In our system we select the “Prices” application.

Then we execute PPR0 condition type

But before we need to change the condition display. This is a very important step. By default, this set material price app is in edit mode, which will lock the price changes. So you neet to set it to display mode first.

Finally we can see that the price has changed to 1104,99 USD.

 

In Conclusion

In this blog post we learned how to create an OData Service in S/4Hana system and how to call it from an analytic application. Because we used OData v4 we were able to udpate values in S/4Hana system direclty from an analytical application. This workfow is called a close loop scenario and it’s very powerful as a business user can explore, analyze and do simulation of its data and take concrete actions from a simple application.

If you want to know more about all the OData services capabilities in Analytics Designer look at the developer handbook.
